JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. Available in 409 or 304 Series Stainless Steel. These long tube designs are dyno and race proven to deliver the greatest possible increase in horsepower and torque throughout the RPM range. All JBA long tube headers feature large mandrel-bent stainless steel primary tubes, oversized exhaust ports, extra thick 3/8 one-piece flanges, and proprietary JBA Firecone® merged collectors for smooth flow. Each system is designed to give the maximum amount of ground clearance possible, so lowered cars do not drag the collectors. 304 Series Stainless Steel headers are built to endure the harshest of environments, ensuring your investment stands the test of time. These headers are embellished with 304 flanges, longer, smoother 304 merged collectors and 304 primary tubing. Our proprietary JBA Firecone has been extended with a longer concave design within the collector for optimal flow. Available in natural finish or a meticulously hand polished mirror finish. Each system includes high quality hardware and thorough instructions for a professional no-leak installation. For closed course competition use only.
